T0 aZZ whom it may oomem- 1 ,Be it known that I, P UL. E. Norms. acitizenof the United States, residing at Wilkinsburg, in the county ofAllegheny and State of Pennsylvania, have invented certainnew. anduseful Improvements in Storage-Batteryv Cases,of which the following .isas pecification. i My invention relates to storagefbattery cases, andparticularly to cases of the type comprising a box or a containerprovided I willdescribe one form of storage battery c'aseembodying myinvention, aiidwill then point out the novel features thereof; inclaims.

In the accompanying drawings, Fig. .1 is a view showing in endelevation, one form of storage battery case embodying my invention.storage battery case shown in Fig. 1. Fig. 3 is a fragmental sectionalView on the plane IIIIII in Fig. 2 looking in the direction indicated bythe arrows. Fig. 4: is a fragmental sectional view similar to Fig. 3 butshowing a modification of the means for securing the handle tothebattery case shown in Figs. 1, 2 and 3 and also embodying myinvention.

Similar reference characters refer to similar parts in each of theseveral views.

Referring first to Figs. 1 and 2 the battery case comprises a bottom B,sides O and A, and two end plates, only one of which,,D, is shown inFig. 2. It is understood that the other end plate of the case is similarin all respects to end plate D and thatthe following discussion withrelation to end plate D is equally applicable to the other end plate.The material of the case may be any conveniently moulded material whichis impervious to the action of battery electrolyte, such as hard rubberor celluloid. This case is u'efeiably made by moulding the sides, endsand bottom in one integral piece of hard rubber. The end plate D isprovided with two downwardly extending holes K, substantially verticaland spaced well toward the sides of the case as shown in the drawing.Communicating with each of these holes K is a horizontal recess G, whichopens outward from the surface of the end plate D. This recess G is bestshown in Fig. 3, and may be of any convenient shape as square S A B T'EBY In operation the. acid of the electrolyte is .often spilled on theupper surfaceof tlie Fig. 2 is a fragmental top view of the" V therecesses F and around the handle E,

and extends beyond the'hole'l but oe s 'lnot communicate withtheinterior .ofth'e ,ery case. The handle E 'comprises a eeder ub ofsomesuitablematerial as'br zi's's o bent into an arch. shape andliavingtyi o 'ub stantially parallelflegjs Boa-mum; "This handleis s'oproportionedthattliepro legs E and E will enter the holes "K 1 a plate Dwith a I snug fit. After ifis'eamg the handle E'in the holes K,moltenflead is poured into the recesses This lead siilifdi fies around 'thehandle legs E"'ai1d E and thus prevents them ram; beaig' eahaiaenabatteryand is likely toflow'forbreep over the end plates D. "Inthiseventwitli only the arrangement thus far explained the acid wouldenter the inevitable small openings where the legs E and E enter theholes K, and would result in corrosion of the metal handle. In myinvention I prevent this by providing the top edge of end plate D withtwo shallow depressions or recesses F. opening into the battery case andeach completely surrounding one leg of the handle E. When the batteryisassembled, sealing compound is poured over the cells and fills thecase up to the top edge D. In so doing this sealing compound flows intothus effectually preventing the seepage of electrolyte into the holes K.The holes K, the passages G and the recesses F may be moulded into thecase or they may be cut in the case after it is manufactured. The handleE may be provided with an indentation E for engaging a battery hold downin the usual manner.

As shown in Fig. 4 I secure the handle in the case by means of apre-cast metal member I which isinserted in each recess G. This memberis provided with a vertical hole I for accommodating the leg E of thehandle E and with a threaded hole I .in- I tersecting hole I andprovided with a set 1 screw J. In assembling this structure, the memberI is inserted in recess G in such manner that hole I registers with holeK. The handle E is then inserted in the end plate D, the leg E passingthrough holes K and I. The set screw J is'then inserted in hole I andforced into the leg of the handle E, clamping this handle in place. The

from this method of construction are that the handle may be easilyremoved torrenewal, and that the handle may be applied 1 after. thebattery is completely assembled but unsealed.

Although I have herein shown and described only tWo forms of storagebattery cases embodying my invention, it is understood that variouschanges and modificationsmay be made therein Within the scope of theappended-claims Without departing from the spirit and scope of myinvention. Having thus described my invention, What I claim is;

1. In combination, a storage battery case, a handle inserted in a Wallof said case, and a recess in said wall surrounding said handle andcommunicating with the interior of said case but not with the exteriorthereof.

- 2. In combination, a storage battery case,

a handle inserted in said case, and means for preventing the entrance ofelectrolyte between said case and said handle.

3. In combination, a storage battery case, a handle inserted in saidcase, and means for producing a liquid tight jointbetween said case andsaid handle.v

4. In combination, a storage battery case having a hole for receiving ahandle and a recess communicating with said hole for receiving meltedlead thereby retaining said handle in said hole.

5. In combination, a Wall of a storage battery case, two holes in saidWall adjacent the abutting sides of the case, a handle having two legsadapted to enter said holes, and

a recess in said Wall surroundingeach of said legs and communicatingwith the interior of the case for containing sealing material.

6. In combination, a storage battery case I having a handle receivinghole, a handle inserted in said hole and a massof acid resistingsubstance surrounding said handle Where the handle enters the case.

In testimony whereof I aflix my slgnature.

PAUL E. NORRIS.
